Multi-Service Tactical Brevity Codes are standardized procedure words used by multiple branches of the military to efficiently communicate complex information through concise, easily understood terms. These codes are a specialized form of voice procedure intended to improve clarity, speed, and coordination in tactical operations.
American/NATO codes The following list outlines standardized American brevity codes employed during joint service operations. This collection excludes terms unique to individual branches. While these codes are not officially binding across services, they are widely recognized and their meanings agreed upon. Their use enhances interoperability and situational awareness among air, ground, sea, and space forces operating at the tactical level. The provided key indicates which communities use specific terms, as some codes may carry different meanings depending on the service or mission context. These distinctions are noted in-line with each brevity code entry.
A
ABORT Cease action or terminate the attack prior to weapons release or event or mission.
[High or Low] ACCURACY Prebriefed criteria is met during geolocation; must be briefed by package commander (or outlined in the special instructions (SPINS)/standards).**
ACTION Initiate a briefed attack sequence or maneuver.[A/A] [A/S] [S/A] [AIR-MAR]
[system] ACTIVE [location, direction] Referenced emitter is radiating at the stated location or along the stated bearing. Electronic intelligence derived.* [A/A] [EW]
ADD [system or category] Add a specific (system) or (electromagnetic order of battle (EOB) category) to search responsibilities.** [EW]
[weapon] AFFIRM FRIENDLY surface-to-air weapons platform are prepared to engage specified target(s) (e.g., BIRD(S) AFFIRM). Opposite of NEGATE.* [S/A]
ALARM Terminate or terminating emissions control procedures. Opposite of SNOOZE.[A/A] [EW] [MAR] [SO]
ALLIGATOR Link-11A or tactical data link Alpha.
ALPHA CHECK Request for confirmation of bearing and range from aircraft to described point.*
ANCHOR [location] 1. Orbit about a specific point. 2. Refueling track flown by tanker.
ANCHORED [location] Turning engagement at the specified location.* [A/A]
ANGELS Height of FRIENDLY aircraft in thousands of feet from mean sea level (MSL).
ANYFACE FRIENDLY command and control (C2) agency when call sign is not known.
ARIZONA No antiradiation missile ordnance remaining.[A/S] [EW]
[direction] ARM CONTACT(S) within a single GROUP that maneuvers outside of the GROUP criteria.[A/A] [AIR-MAR]
AS FRAGGED Unit or element will be performing exactly as briefed or scheduled.*
ASLEEP No longer detecting land or surface emitter activity via communications intelligence. Opposite of AWAKE.** [EW]
ATTACK An informative call indicating aircraft are committed to air-to-surface delivery on a specific ground target. Note: Not to be used in a close air support (CAS) engagement.* [A/S]
AUTHENTICATE To request or provide a response for a coded challenge.
AUTOCAT Any communications relay using automatic retransmissions.
AVALANCHE Informative call indicating friendly forces require reinforcement in a specific location.** [A/A] [AIR-MAR]
AWAKE Land or surface emitter activity detected via communications intelligence. Opposite of ASLEEP.** [EW]
[number, weapon type] AWAY Release or launch of specified weapon (e.g., 1 AWAY, 2 PIGS AWAY, BIRDS AWAY, etc.). At minimum, number or weapon type required. Note: Include launch location in BULLSEYE format and weapons track direction when appropriate.[A/S] [AIR-MAR] [S/A]
AZIMUTH 1. A picture label describing two GROUPS separated laterally. GROUP names will be referenced by cardinal directions (e.g., NORTH GROUP, SOUTH GROUP, or EAST GROUP, WEST GROUP).[A/A] [AIR-MAR] 2. Direction to the threat.** [A/A] [S/A]
B
BAD MAP Call that the displayed map is unusable due to the following: Terrain - call that shadows obstruct the target area and a map must be taken from a different axis or graze angle. Image - call that the displayed image quality prevents target identification (ID).** [A/S]
BANDIT 1. Positively identified as an enemy in accordance with (IAW) theater ID criteria. The term does not imply direction or authority to engage.[A/A] [AIR-MAR] 2. A SUSPECT whose orbital parameters are such that it may become a collection and/or counterspace concern to a spacecraft in the relative near-term, therefore limiting decision space.* [SO]
BANZAI Execute(ing) launch and decide tactics with the intent to maneuver into the visual arena.* [A/A]
BASE [+/- number] Reference number used to indicate such information as headings, altitude, fuels, etc.
BAT(S) FRIENDLY net-enabled glide weapon(s) with a multi-mode seeker (e.g., standoff weapon, guided bomb unit, small diameter bomb).** [A/S]
BAY Carry out deception plan indicated or IAW previous orders.[EW]
BEAD WINDOW Last transmission potentially disclosed unauthorized information.*
BEAM [direction] CONTACT stabilized within 60-109 degrees angle of trail or 71-120 degrees angle from nose.[A/A]
BEAM RIDER [direction] Potential JAMMER along the stated azimuth from a ground unit or aircraft stated from the unit or aircraft's location. Usually followed by a request to search using an alternate radar source.** [A/A] [A/S]
[system] BENT System indicated is inoperative. Cancelled by SWEET.*
BERETTA Aircraft is out of or unable to employ remaining air-to-ground ordnance, not to include gun (if equipped).** [A/S]
BIG STICK FRIENDLY long-range surface-to-air missile(s) (SAM(s)). Modifiers include: AWAY, NEGATE, AFFIRM.** [S/A]
BINGO Prebriefed fuel state needed for recovery.*
BIRD(S) FRIENDLY SAM(s). Modifiers include: AWAY, NEGATE, AFFIRM.[S/A]
BIRDDOG Call to configure sensors IAW mission planning/brief.**
BITTERSWEET Notification of potential for blue-on-blue (friendly fire) or blue-on-neutral situation.**
BLACKOUT 1. Turn off all external lighting.** [A/A] 2. Surface ship radar is unable to effectively search or transition tracking to a new object due to over saturation.** [MAR]
BLANK Signal is on the air with zero content.** [SO]
BLIND No visual contact with FRIENDLY aircraft, ship, or ground position. Opposite of VISUAL.
BLOCK An inherently defensive tactic used to force a vessel to alter course away from the defended asset or stop its closure. It is accomplished by maneuvering a unit directly in front of the closing vessel and maintaining position. The possibility of collision exists, depending on the intent of the closing vessel.** [MAR]
